Interesting concept! It took me three tries to figure out what to do—I think adding a few GIFs or a quick guide to the description would really help new players. I managed to get the viruses to the heart, but then the game just went to a black screen (I'm playing on Firefox). Not sure if that was the ending or a bug, but a 'Victory' or 'Game Over' screen would be a great addition. On the plus side, the music is really cool and fits the vibe! Good luck with future updates!
